The gold work is handmade by a master goldsmith of 18 karat yellow gold in the Mid-19th century. The method used would have been the "Lost Wax Method" of jewelry design.
Information on Lost-wax casting (also called "investment casting", "precision casting", or cire perdue in French) is the process by which a duplicate metal sculpture (often silver, gold, brass or bronze) is cast from an original sculpture. Intricate works can be achieved by this method.

The oldest known example of this technique is a 6,000-year old amulet from Pakistan.[1] Other examples from a similar period are the objects discovered in the Cave of the Treasure (Nahal Mishmar) hoard in southern Israel, and which belong to the Chalcolithic period (4500–3500 BC). Conservative estimates of age from carbon-14 dating date the items to c. 3700 BC, making them more than 5,700 years old.[2][3]. The lost-wax casting was widespread in Europe until the 18th century, when a piece-molding process came to predominate.

The steps used in casting small bronze sculptures are fairly standardized, though the process today varies from foundry to foundry. (In modern industrial use, the process is called investment casting.) Variations of the process include: "lost mould", which recognizes that materials other than wax can be used (such as tallow, resin, tar, and textile);[4] and "waste wax process" (or "waste mould casting"), because the mold is destroyed to remove the cast item, so each item made by this method is a one of a kind work of Art.
The earrings are set with three natural ocean pearls at 4.5 mm each in each earring. The Pearls are hand drilled and strung on gold wire.
Information on Pearls:
The ocean pearls came from the Mediterranean Sea and were very laborious to retrieve and then they had to find matching sizes and colors for the setting of this pendant.
Pearl History: Pearls, in fact, played the pivotal role at the most celebrated banquet in literature. To convince Rome that Egypt possessed a heritage and wealth that put it above conquest, Cleopatra wagered Marc Antony she could give the most expensive dinner in history. The Roman reclined as the queen sat with an empty plate and a goblet of wine (or vinegar). She crushed one large pearl of a pair of earrings, dissolved it in the liquid, and then drank it down. Astonished, Antony declined his dinner—the matching pearl—and admitted she had won. Pliny, the world's first gemologist, writes in his famous Natural History that the two pearls were worth an estimated 60 million sesterces, or 1,875,000 ounces of fine silver ($9,375,000 with silver at $5/ounce). In the Georgian time period and much earlier, finding a valuable pearl requires as much luck as skill. And in their quest for both pearls and mother-of-pearl, people have sometimes taken extraordinary measures. For many centuries, divers for marine pearls had to outmaneuver sharks and other dangers to locate the pearl oysters they hoped would contain natural pearls. The small seed pearl was desired by England and the Eastern United States. We 21st Century people take a lot for granted when it comes to gems and pearls and fine jewelry. In the 18th and 19th centuries, these works of art were treasures to be kept in the family.
